Long table centerpiece items

Hi everyone,


I’m looking for some advice on my table centerpiece. We’re having a very small wedding, around 27 people, we’ve decided to just have one long table which is 4 6ftx5ft tables together, with two half round ones on each end. I need help deciding how many decor items I need to fill the space. I wanted to use a table runner with 4 small hand tied bouquets and 3 large potted orchids, and some candle holders. Does anyone have a general guide as to how many candles I need or if I need more flowers or anything. I don’t want the table to look too empty.
Thank you!
